The Pixelblaze V3 Standard XL is a Wi-Fi addressable LED controller powered by an ESP32 dual-core processor at 240 MHz. It includes a web-based live pattern editor that lets you write, preview, and store LED patterns using a JavaScript/C-like expression engine — all from your browser with no software installation required.
This is the XL variant with 16 MB flash and 8 MB PSRAM for extended pattern storage and data. The Standard version adds GPIO, analogue, and touch inputs for interfacing with external hardware and sensors, plus support for an optional Sensor Board with a microphone, accelerometer, light sensor, and music-reactive co-processor.
Key Features
- Wi-Fi Pattern Editor – Write and preview LED patterns live in your browser with instant feedback
- ESP32 Dual-Core – 240 MHz processor for fast pixel rendering
- XL Memory – 16 MB flash + 8 MB PSRAM for storing over 100 patterns
- 2D/3D Pixel Mapping – Map arbitrary LED layouts in 2D or 3D space; patterns adapt automatically to different installations
- UI Controls – Add sliders and colour pickers to patterns with a single function
- Hardware Inputs – GPIO, analogue, and capacitive touch for sensor integration
- Community Patterns – Over 200 ready-made patterns available to load or customise
- Beginner-Friendly – Real-time feedback, variable watcher, and graceful error handling make patterns easy to write and debug
Ideal For
- LED art installations — large and small
- Costumes, wearables, and cosplay lighting
- Vehicle and architectural LED decoration
- Interactive and music-reactive LED projects (with optional Sensor Board)

Jargon buster
Plain-language definitions for the technical terms used above.
- ESP32
- ESP32 is a family of low-cost microcontroller chips and modules from Espressif with built-in WiFi and Bluetooth. They support programmable firmware and over-the-air updates, and are commonly programmed with toolchains such as the Arduino core and ESP-IDF.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
